These unused comparison operators are the only users of
<functional> in SkRefCnt.h, for std::less. <functional>
is an expensive header to compile, and SkRefCnt.h is popular,
so it helps to cut dependencies like this.
Mostly we just need to add #include <functional> in a few
places that were picking it up via SkRefCnt.h.
In SkPixmapPriv.h, it looked simpler to template the argument,
since everything was inline anyway.

That makes layout phase 10 times faster (since the shaping takes 90% of it).
LRU cache is attached to the FontCollection object and has the same life time.
Currently it has hardcoded limit on the entry numbers (128).
One the number reached, the least recently used element is removed from the cache
to free the space for a new one.
